Study Notes
Flow Oriented Devices and Volume Oriented Devices
- Devices for airway clearance can be categorized as either flow oriented or volume oriented.
Potential Outcomes of Spirometry
- Spirometry can identify the presence of atelectasis.
- Spirometry can measure vital capacity (VC) and volume.
- Spirometry can track changes in respiratory rate and pulse rate.
- Spirometry can assess the effectiveness of lung expansion therapy.
Devices/Techniques for Lung Expansion Therapy
- Non-invasive ventilation (NIV) was first developed in the early 1980s.
- NIV provides breathing support for patients with inadequate ventilation.
- NIV is effective for patients with chronic obstructive pulmonary disease (COPD).
- NIV can help reduce the risk of infections and sedation compared to invasive ventilation due to the absence of an artificial airway.
Contraindications for Non-invasive Ventilation (NIV)
- There are no absolute contraindications for NIV.
- NIV should be avoided in patients with increased intracranial pressure (ICP) above 15 mmHg.
- NIV is not recommended for patients with active hemoptysis, hemodynamic instability, recent facial, oral, or skull surgery, tracheoesophageal fistula, active untreated tuberculosis, radiographic evidence of bleb, or singultus (hiccups).
Hazards and Complications of Non-invasive Ventilation (NIV)
- Possible hazards and complications include increased airway resistance, barotrauma, pneumothorax, nosocomial infection, psychological dependence, impedance of venous return, exacerbation of hypoxemia, hyperventilation or hypocapnia, hypoventilation, hemoptysis, increased V/Q mismatch, hyperoxia, gastric distention, and air trapping.
Devices/Techniques for Lung Expansion Therapy
- Positive airway pressure (PAP) therapy uses positive pressure to increase the pressure gradient and improve lung expansion.
- PAP therapy does not require complex machinery.
Percussion
- Percussion can be used to enhance secretion clearance and shorten treatment duration.
- Percussion may not be well-tolerated by patients postoperatively without adequate pain control.
- Percussion can pose a risk to patients with osteoporosis or coagulopathy.
- Percussion can lead to a decrease in oxygen saturation.
- Percussion could lead to repetitive motion injuries for caregivers who provide long-term treatments.
Vibration
- Vibration is another method to loosen or move bronchial secretions.
- Vibration can be manual or mechanical.
- It is performed in postural drainage positions to clear secretions.
- Vibration can be used to assist patients with neuromuscular diseases (NMD) to generate sufficient expiratory flow rates for secretion clearance.
PEP Therapy
- Positive expiratory pressure (PEP) therapy involves active expiration against a fixed or variable orifice flow resistor.
- PEP therapy is designed to prevent airway collapse during expiration and facilitate mucus clearance.
High-Frequency Positive Airway Pressure Devices
- High-frequency positive airway pressure devices use rapid pressurized gas mini-bursts to clear airways.
- These devices allow patients to inhale and exhale while the oscillating airway pressure is applied.
High-Frequency Chest Wall Oscillation (HFCWO) Devices
- HFCWO devices use a vest system to create pressure pulses against the thorax, leading to chest wall oscillations.
- HFCWO devices are typically used for 30-minute sessions 2-6 times per day.
Suctioning
- Suctioning is an invasive technique for the removal of airway secretions.
- Suctioning involves applying negative pressure to the airway through a collecting tube.
- The normal suction pressure for adults is less than 200 mmHg.
